[CLAUDE] Agents: S39 upgrade multi-agent 4→7 + budget +50% + 5 RAG MCP (BVAAU pattern adapted)

Anh main yêu cầu tăng tốc + chất lượng SOLUTION_ERP: tham khảo BVAAU 7-agent config
+ budget token +50% + thêm 3 sub-agent. Adapted (NOT copied) — SOLUTION_ERP 2-FE-app
fit + giữ 6 skill proven battle-test 38 session.

Split 4→7 agent (anh main chốt via AskUserQuestion):
- investigator → SPLIT: investigator-codebase (cyan, internal SQL/EF/grep) +
  investigator-api (blue, external docs/CVE/lib/cross-project)
- implementer → SPLIT: implementer-backend (yellow, .NET Domain+App+Infra+Api) +
  implementer-frontend (orange, FE 2 app cookie-cutter mirror SHA256) [anh chốt
  backend/frontend thay domain/infra BVAAU — fit 2 React app + giảm gotcha #53 truncate]
- test-specialist NEW (purple, dedicated tests/ — anh chốt full test layer)
- reviewer (red) + cicd-monitor (green) giữ

Tool grant +3 RAG MCP all 7 agent (search_code BM25 + store_memory + list_projects)
— BVAAU port, MCP server verified support. Prior chỉ 2 (search_memory + cross_project).

Skill re-distribute 6 skill across 7 agent (xem README matrix).

Memory: rename investigator→investigator-codebase + implementer→implementer-backend
(giữ history) + seed 3 new MEMORY (investigator-api/implementer-frontend/test-specialist)
extract relevant patterns. Delete old investigator.md + implementer.md.

README rewrite: 7-agent architecture + decision tree split-routing + phân việc matrix
boundary + token budget +50% cost reality (~1.05M opt / ~2M heavy ceiling) +
anti-truncation rules (gotcha #53 5× mitigation: brief ≤8K + curate pre-spawn +
entry ≤1.5K + 529 fallback solo).

⚠️ Anh main RESTART Claude Code CLI để registry hot-reload 7 agent (per S27 lesson
model:inherit + new files). Verify post-restart: smoke spawn 3 new agent confirm load.

+
+## 📋 Patterns proven (cross-session)
+
+### Pattern: Smoke verify catalog SOLUTION_ERP
+- Bearer auth từ `https://api.solutions.com.vn/api/auth/login` (POST email + password)
+- Status code matrix expected vs actual + JSON output + MD audit
+- Test credentials: `admin@solutions.com.vn / Admin@123456` (full) OR `nv.test@solutions.com.vn / TestUser@123456` (Drafter UAT scope)
+
+### Pattern: Schema scan via sqlcmd
+```bash
+# LocalDB Dev (runtime — primary)
+sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Dev -Q "..."
+
+# LocalDB Design (ef tooling)
+sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Design -Q "..."
+
+# Production (qua SSH vietreport-vps)
+ssh vietreport-vps "sqlcmd -S .\SQLEXPRESS -d SolutionErp -U vrapp -P '...' -Q '...'"
+```
+Common queries: `sys.columns`, `sys.triggers`, `__EFMigrationsHistory`, `COUNT(*)`, `sys.indexes`.
+
+**Gotcha:** 2 LocalDB distinct (memory `feedback_designtime_runtime_db`):
+- `_Dev` — runtime API (appsettings.Development.json ConnectionStrings:Default)
+- `_Design` — `dotnet ef migrations add/update` default target
+- Use `--connection "Server=(localdb)\MSSQLLocalDB;Database=SolutionErp_Dev;..."` override khi cần Dev specifically.
+
+### Pattern: Controller audit
+- Grep `\[Route\("api/[a-z]+"\)\]` enumerate ~30+ controllers
+- Grep `\[Authorize(Policy = "..."` audit per-action policy (gotcha #44 silent 403 class-level quá strict)
+- Grep `IActionResult` vs `ActionResult<T>` — typed return preferred
+- Grep `// Mock` / `alert(` / `setEditing(null) // close UI` — wire claim bugs
+
+### Pattern: Memory cross-reference
+19 memory entries tại `C:\Users\pqhuy\.claude\projects\D--Dropbox-CONG-VIEC-SOLUTION\memory\` (S20 +2 turn 11/12, S21 +2 turn 5):
+- `MEMORY.md` — index
+- `project_solution_erp.md` — cumulative narrative S1-S17
+- `feedback_per_chunk_commit.md` — 5-chunk A-E discipline
+- `feedback_uat_skip_verify.md` — Phase 9 skip test rule
+- `feedback_drastic_refactor_scope.md` — defer dedicated session
+- `feedback_audit_reuse_before_clone.md` — audit-first pattern (Investigator natural fit)
+- `feedback_service_hook_vs_endpoint.md` — derived state hook pattern
+- `feedback_n_stage_workflow_pattern.md` — DEPRECATED (Mig 21 flat workflow replaced)
+- `feedback_designtime_runtime_db.md` — 2 LocalDB distinct
+- `feedback_md_compact_narrative.md` — §6.5 KEEP narrative rule
+- `feedback_unittest_timing.md` — §7 test timing
+- `feedback_cron_monthly_limitation.md` — Cron SDK 7-day expire
+- `feedback_user_manual_style.md` — non-tech docs style
+- `feedback_node_cicd.md` — Node 20.x pin
+- `feedback_responsive_laptop_breakpoint.md` — 4-tầng responsive pattern (S20 t11)
+- `feedback_multi_agent_setup.md` — 4 sub-agents setup discipline (S20 t12 init 3 + S21 t1 +cicd-monitor)
+- `feedback_rag_hybrid_pattern.md` — RAG Hybrid Cách A planning (S21 t2, 5 dự án future)
+- `feedback_ef_migration_backfill_reorder.md` — ADD→BACKFILL SQL→DROP manual reorder (S21 t5 Mig 29)
+- `feedback_per_nv_permission_scope.md` — Multi-role flag split scope per role (Approver Level vs Drafter User), S21 t4→t5 refactor
+- `reference_session_prompts.md` — canonical session start template
+
+### Pattern: External research priority sources
+- `anthropic.com/engineering/` (official patterns)
+- `cognition.ai/blog/` (Devin lessons)
+- `philschmid.de` + `eugeneyan.com` + `hamel.dev` (senior engineers)
+- `learn.microsoft.com/en-us/aspnet/core/` (.NET 10 official)
+- `tanstack.com/query/latest` (TanStack Query)

+
+## ⚠️ Anti-patterns observed
+
+- ❌ Skip MEMORY.md update before stop — lose knowledge tài sản
+- ❌ Vague conclusion "seems like" / "probably" — em main rejects
+- ❌ Missing file:line refs — non-verifiable evidence
+- ❌ Exceed 500 words — em main reads too slow
+- ❌ Scope drift to architectural recommendations — em main decides, not me

+Investigator agent initialized. Baseline knowledge load complete (44 gotchas + 14 memory entries + 6 skills + 27 mig + 81 test pass cumulative). No investigations performed yet. Awaiting first SendMessage from em main.
+
+### 2026-05-13 (S21 t3-t5, no spawn)
+
+Em main solo 3 turns (bug fix gotcha #45 + F1+F2+F3 workflow-level Mig 28 + refactor per-NV Mig 29). Implementer REFUSE per cross-stack reasoning chain rule. Investigator KHÔNG spawn — em main đã có context cumulative S20 t12 setup + active dev throughout. No findings to flush. Cumulative state update: 84 test, 29 mig, 45 gotcha, 19 memory entries (+2 S21 t5 pending), 6 skills unchanged. Pattern reusable saved cho future spawn: per-NV permission scope split + EF migration ADD→BACKFILL→DROP reorder.
+
+### 2026-05-13 (S22, no spawn — em main solo throughout)
+
+S22 18:00→~21:00 em main solo.

Prod active users 13→33 (+20 role-based: act.nv/pp/tp, bod.1/2, equ/fin/hra/pm/qs.nv/pp/tp).
+
+**Discoveries S22:**
+1. **Per-NV admin opt-in flag pattern reinforced 2×** — Mig 30 F4 cùng pattern Mig 29 F1+F3 (S21 t5). Bro corrected em main lần đầu: "phải tick checkbox như Section 2", default = admin opt-in per slot, KHÔNG = mở rộng default. Cross-ref memory `feedback_per_nv_permission_scope.md` proven 2×.
+2. **Plan F drop V1 ABORTED** — pre-flight sqlcmd reveal Contract entity HOÀN TOÀN V1 chưa wire V2 (chưa có ApprovalWorkflowId column) + 4 PE V1-only + 19 PE V1+V2 mix. Lesson: drop migration cần verify entity scope toàn bộ (Contract liên đới — không chỉ PE).
+3. **Identity password policy ≥12 chars** — seed 20 user FAIL 400 với "User@123456" (11 chars), `TestUser@2026` (13 chars) pass.
+4. **Identity rename atomic 4 fields** confirm gotcha #38: Email + NormalizedEmail + UserName + NormalizedUserName + FullName; sqlcmd cần `SET QUOTED_IDENTIFIER ON` cho filtered unique index.
+5. **API login response field name `accessToken` + `refreshToken` + `user`** — KHÔNG có field `token` (correct prior Bash example trong spec dùng `.token` sẽ fail).
+6. **PS 5.1 ASCII-only script discipline** reinforced gotcha #30: `seed-test-users-prod.ps1` viết Vietnamese names without diacritics tránh parser error. Recommend bro add 1 memory entry "Admin opt-in flag pattern proven 2×" cumulative Mig 29 + Mig 30.

Audit 4 BE file + 4 FE file × 2 app cho F1+F2+F3+F4 phase semantic ChoDuyet preservation. **Verdict: CODE ĐÃ ĐÚNG semantic mới — đây là DISCONNECT bro mental model vs code reality post-Mig 28/29/30/31.** Evidence per feature: **F1.OneLevel** `PurchaseEvaluationWorkflowService.cs:285-312` SWITCH branch lùi 1 Cấp cùng Step (`curLevel-1`) ELSE lùi Step trước Cấp cuối; **Phase KHÔNG đổi** (giữ ChoDuyet, line 364 reset SLA only); fallback Drafter `:303-310` CHỈ KHI đang Bước 1 Cấp 1 no further back (clear pointer + Phase=TraLai). **F1.Assignee** `:335-360` foreach Steps find ApproverUserId match → set pointer; Phase giữ ChoDuyet; ConflictException nếu không tìm thấy NV trong workflow. **F1.OneStep** `:314-333` lùi prev Step Cấp max; Phase giữ ChoDuyet; fallback Drafter nếu đang Bước 1. **F1.Drafter** `:268-275` SET `Phase=TraLai=98` + clear cả 2 pointer + SLA null — đây là CASE DUY NHẤT về "draft". **F2 skipToFinal** `:483-524` Plan K L1 ĐÃ FIX advance pointer tới Bước cuối Cấp cuối (max), **Phase giữ ChoDuyet** (NV cuối duyệt thật để DaDuyet); guard line 485 ConflictException non-admin + flag off; opinion UPSERT trước line 441-468 ensure actor's signature lưu trước. **F3 EnsureEditableForDetailsAsync** `PurchaseEvaluationDetailFeatures.cs:42-99` 2 trường hợp accepted: Drafter scope (DangSoanThao/TraLai return pe sớm line 49-51) **OR Approver scope ChoDuyet line 54-94** (V2 schema + actor match level.ApproverUserId + level.AllowApproverEditDetails flag). **F4 AdjustPurchaseEvaluationBudgetCommandHandler** `PurchaseEvaluationFeatures.cs:272-329` Drafter scope `:283-290` (DangSoanThao/TraLai + isDrafter) ELSE Approver scope ChoDuyet `:291-323` (V2 + pointer init + actor match + level.AllowApproverEditBudget flag) — Phase ChoDuyet đã handle full. **Validation Allow* flag location** `PurchaseEvaluationWorkflowService.cs:252-265` ApplyReturnModeAsync gate per slot per mode: throw ConflictException nếu disabled (Admin bypass line 252). **FE PeWorkflowPanel.tsx**: TraLai dialog `:331-422` 4 radio button (OneLevel/OneStep/Assignee/Drafter) gated bằng `levelOptions?.allowReturnXxx` flag per current Approver Cấp (line 343-396); useEffect `:60-68` S23 t2 fix default first available mode KHÔNG Drafter khi admin tick F1 modes. Skip Final checkbox `:425-442` chỉ visible khi `levelOptions?.allowApproverSkipToFinal` + Approve forward direction (line 425). **FE PeDetailTabs.tsx F3+F4 wire**: `itemsReadOnly = readOnly && !approverEditMode` line 118 bypass readOnly khi F3 enabled (Mig 28 pattern); `canAdjust = isAdmin || (!readOnly && isDrafter && isDrafterPhase) || isApproverChoDuyet` line 977 bypass readOnly khi F4 enabled (L2 fix). Mirror fe-admin/fe-user line 109-115 + 967-979 ĐỒNG BỘ rule §3.9. **Surprise**: "Trả lại" trong UI memory docs đôi khi gọi "draft" colloquial — bro confuse 2 khái niệm `Phase=TraLai=98` (Drafter sửa rồi gửi LẠI từ Step 0) vs `Phase=DangSoanThao=1` (chưa từng gửi duyệt). KHÔNG code path nào trong F1 OneLevel/OneStep/Assignee/F2/F3/F4 set targetPhase=DangSoanThao mà không nên. **Recommendation: LOW effort** (0-20 LOC): chỉ cần communication clarification em main confirm với bro 4 mode F1 + F2 + F3 + F4 đã giữ Phase=ChoDuyet trừ F1.Drafter; mở DB SELECT phiếu UAT confirm `Phase` column number sau click test; OPTIONAL touch up FE label nếu user thấy "Đã gửi duyệt" nhầm "Bản nháp". KHÔNG cần Service refactor hay handler change. Nếu bro thấy phiếu cụ thể về Phase=1 SAU click F1.OneLevel hoặc F2 → spawn lại Investigator audit DB state + log Changelog cho phiếu đó cụ thể (data debug, not code bug).
+
+### 2026-05-15 (S23 t3 spawn — UAT bug Allow* flags không hiện cho actor non-row1)
+
+Bro UAT login `nv.test@solutions.com.vn` vào menu eoffice "Duyệt NCC → Duyệt" phiếu PE/2026/A/026 (Phase=ChoDuyet, WF=QT-DN-V2-001 v12, ở Bước 2 Cấp 1 4 NV: Trần Xuân Lưu/NV Test UAT V2/Hồ Thị Nữ Nguyên/Lê Văn Bính). Admin ĐÃ tick 7 Allow*=TRUE riêng cho slot NV Test UAT V2. Nhưng FE dialog Duyệt KHÔNG hiện checkbox SkipToFinal + Trả lại 4 mode + Edit. **Verdict: HYPOTHESIS B — BE handler picks wrong slot row.** Evidence: (1) `PurchaseEvaluationFeatures.cs:765` `var curLevel = curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder);` — match FIRST row có `Level.Order == curLevelOrder`, NOT actor's row. Post-Mig 29 refactor, Level.Order trùng nhau cho mọi NV cùng Cấp (4 row có `Order=1` ở Step 2). EF returns Trần Xuân Lưu trước (PK order) → `FirstOrDefault` lấy row đó (all-false except Drafter=true). (2) API curl admin token + nv.test token return CÙNG `currentLevelOptions={ allowReturnOneLevel=false, OneStep=false, Assignee=false, Drafter=true, EditDetails=false, EditBudget=false, SkipToFinal=false }` — handler currentUser-agnostic confirm. (3) Workflow detail GET `/approval-workflows-v2?applicableType=1` `.types[0].active.steps[1].levels` enumerate 4 slot Bước 2 Cấp 1: NV Test (UAT V2) = ALL 7 TRUE; 3 NV còn lại = ALL FALSE (trừ Drafter=true mặc định). Admin Designer wire ĐÚNG (`fe-admin/src/pages/system/ApprovalWorkflowsV2Page.tsx:889-946` 7 checkbox per-slot). FE consumer wire ĐÚNG (`fe-user/src/components/pe/PeWorkflowPanel.tsx:51 levelOptions = evaluation.currentLevelOptions` + line 343/357/371/397 conditional render mode picker + line 425 SkipToFinal checkbox). **Root cause:** BE line 765 lookup semantic broken sau Mig 29 (S21 t5). Trước Mig 29, 1 Level row per Cấp + `ApproverUsers` join table → `FirstOrDefault(Order==X)` đúng. Sau Mig 29 split 1 Level row PER ApproverUser → `Order` field collide → cần match thêm `ApproverUserId == currentUser.UserId`. **Fix BE 1 dòng:** `var curLevel = curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder && l.ApproverUserId == currentUser.UserId);` (admin bypass: fallback `?? curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder)` để admin xem detail không lỗi). Edge case: Phase=DaDuyet/TraLai/TuChoi pointer null → existing guard line 760-762 skip block OK. **LOC ~2-3 LOC 1 file.** Surprise: bug PRESENT từ deploy Mig 29 (S21 t5 2026-05-13) — không phải regression S23. Lý do trước đây không bắt: UAT test users (default 13 cũ) đa số là row đầu của slot Cấp (Admin tick toàn FALSE → behavior giống nhau, không lộ); chỉ bộc lộ khi admin tick CHỌN LỌC per-NV (UAT V2 S22+2 thêm 20 user role-based + bro tick chỉ NV Test UAT V2). Cross-reference memory `feedback_per_nv_permission_scope.md` cumulative S21 t5 → S22+5 → S23 t1 — KHÔNG có entry nào nhắc bug lookup BE post-refactor.
+
+### 2026-05-15 (S23 t6 spawn Plan P FE wire audit — confirm BE-only scope)
+
+Em main hypothesize Plan P scope BE Controller body record drop. Investigator audit FE × 2 confirm: `PeWorkflowPanel.tsx:113-124` `api.post(/transitions, body)` SEND ĐÚNG 7 fields (TargetPhase + Decision + Comment + ReturnMode + ReturnTargetUserId + SkipToFinal). No service file (untyped object literal). BE `PurchaseEvaluationsController.cs:267` `TransitionPeBody` record CHỈ 3 fields → ASP.NET silent DROP 3 missing fields. Verdict: Plan P BE Controller ONLY ~6 LOC + no test (Mig 28/31 Domain test cover handler). Saved em main blind fix cross-stack.
+
+### 2026-05-15 (S23 t8 spawn Plan R pre-flight cleanup audit)
+
+Bro chốt cleanup destructive prod. 4 sqlcmd queries audit: 35 PE total (28 active + 7 soft) + 17 V2 (15 IsUserSelectable=false + 2 ghim) + 4 V1 (2 active + 2 inactive). FK gotcha catch: PE.ApprovalWorkflowId Restrict + ApprovalWorkflow extends `BaseEntity` NO soft-delete → hard-DELETE required; LevelOpinion → ApprovalWorkflowLevel Restrict cascade block. SQL Express limit: NO COMPRESSION + RESTORE VERIFYONLY require sysadmin. Filtered indexes (Mig 29+) require `SET QUOTED_IDENTIFIER ON`. Cascade child estimate: 446 PE children + ~140 V2 + ~37 V1 = ~620 rows. 3 Option compare → bro chốt A (Hard-DELETE PE + V2 unghim + V1 inactive, GIỮ V2 ghim + V1 active). Plan F precedent: KHÔNG drop V1 active (PE pin → BE crash).
+
+### 2026-05-15 (S24 t1 spawn Pre-A — Plan AA User Workflow Matrix view + sidebar widen)
+
+5Q audit. Q1 endpoint: `ApprovalWorkflowsV2Controller.cs:16-19` đã class-level `[Authorize]` bare từ S18 2026-05-08 (gotcha #44 fixed permanent), per-method admin Workflows.Create. Handler `GetAwAdminOverviewQuery` KHÔNG có IsUserSelectable filter — cần ADD param + Where conditional. Q2 menu seed: `DbInitializer.cs:1429-1437` peOrder global increment (Group=1, leaves 2/3/4 cycle per type). Permission seed `line 1541-1547` cho 7 role (Drafter/DeptManager/Procurement/CostControl/ProjectManager/Director/AuthorizedSigner). Accounting NOT trong list — admin manual grant nếu cần. Q3 Admin Designer: `ApprovalWorkflowsV2Page.tsx` 975 lines, AwLevelDto 13 fields (7 Allow*), VI labels line 892-948 ("Trả về 1 Cấp trước"/"Trả về 1 Bước trước"/"Trả về Người chỉ định"/"Trả về Drafter (mặc định)"/"Cho phép chỉnh sửa Section 2 (Hạng mục/NCC/Báo giá) lúc đang duyệt"/"Cho phép chỉnh sửa Section ngân sách lúc đang duyệt"/"Cho phép duyệt thẳng Cấp cuối khi đang duyệt"). KHÔNG có usePermission/PermissionGuard wrap (class-level [Authorize] route guard sufficient). Q4 sidebar widen: fe-user `Layout.tsx:325` + fe-admin `Layout.tsx:218` `w-60 xl:w-72` (240/288px). PE Workspace 2-panel `[260px_1fr] xl:[320px_1fr]` (NOT 3-panel như memory `feedback_responsive_laptop_breakpoint` stale claim). After widen `w-72 xl:w-80` (288/320px) SAFE (sidebar 288 + main 992 → workspace 260+732 fit @ 1280px). `w-80 xl:w-96` THRESHOLD RISKY (sát 700px remaining). Q5 ApplicableType enum `ApprovalWorkflow.cs:45-50` {DuyetNcc=1, DuyetNccPhuongAn=2, Contract=3}. Surprises: (1) memory responsive breakpoint stale "3-panel" → cần update sau Plan AA. (2) Order strategy "Luồng duyệt" Order=2 first → shift existing leaves +1 → cần DbInitializer UPDATE Order existing (KHÔNG chỉ INSERT-if-not-exists). (3) Contract=3 chưa wire FE (chỉ DuyetNcc + DuyetNccPhuongAn). Recommendation: Proceed Plan AA — chỉ ADD param filter + 1 menu key + page mới + sidebar widen. Token cost ~32k.
+
+### 2026-05-15 (S24 t1-t4 post-spawn, em main solo 4 polish chunks — Plan AA wrap)
+
+7 commits total `a1a910f..ee0902a`: BE+Layout (`ee776d5`) + FE Page (`c667802`) + Docs (`ac2c859`) + 4 polish iter UAT (`da218f1` px-2 + `4d60598` v1 panel-per-NV + `fbbd361` v2 table rowSpan + `ee0902a` sidebar label wrap). **Pattern reusable**: `inline-block icon + inline text + absolute ChevronDown` cho hanging-indent reverse wrap (label dài về đầu hàng). Mirror admin Designer style cho user view read-only. **Sidebar widen tradeoff**: `w-72 xl:w-80` + remove `truncate` FAIL fit 44+ chars label custom Mig 27 — cần combine với `text-[12px] + leading-snug` + restructure flex → block + inline. Sole `truncate` removal không đủ — phải full layout restructure NavLink. **Memory drift confirmed**: `feedback_responsive_laptop_breakpoint.md` claim "PE Workspace 3-panel" → S24 verify ACTUAL **2-panel** (260+1fr only, KHÔNG có panel thứ 3). Cross-ref update needed memory user-level (admin trigger curate sau). **Plan AA color palette success**: STEP_PALETTE 5 màu (blue/purple/emerald/amber/pink) + LEVEL_PALETTE 5 màu (violet/sky/teal/orange/rose) — **Tailwind JIT yêu cầu full class strings array, KHÔNG dynamic interpolation** (`bg-${color}-100` FAIL — class purged). Reusable cross-project cho menu hierarchy color coding (step parent + level child distinct palette). Final layout v2 table rowSpan: Step column merge per-Phòng + Level column rowSpan per-Cấp + NV column 1-row-per-approver, đẹp hơn v1 panel-per-NV stacked. Token cost iteration negligible (em main solo, no spawn).

+
+Em main report 2 bug UAT: (1) Budget Adjust 2×click → "Lịch sử thay đổi" KHÔNG show 2 entry. (2) Return Assignee mode F1 click → "Lịch sử thay đổi" KHÔNG show return action. Audit 5Q: Q1-DB state Prod SSH fail (auth), fallback code inspect. Q2-Budget handler: `PurchaseEvaluationFeatures.cs:379-387` **ĐÃ log changelog** EntityType=Header + Action=Update + summary diff → **code ĐÚNG, likelihood FE filter bug or UAT DB stale**. Q3-Return handler: `PurchaseEvaluationWorkflowService.cs:215-378 ApplyReturnModeAsync` **ZERO changelog log** — 4 mode branches (OneLevel/OneStep/Assignee/Drafter) mutate pointers only, return summary, caller `TransitionAsync:100 LogTransitionAsync` only logs phase transition KHÔNG log mode side-effect. Q4-Schema: `PurchaseEvaluationChangelog.cs` support EntityType=Workflow(5) enum but **ZERO code populate** — schema incomplete missing Kind/ChangeType subtype enum to disambiguate "budget adjust" vs "detail edit" vs "return mode" (all Header/Workflow entity cùng Action.Update). Q5-FE: Query handler `ListPurchaseEvaluationChangelogsQueryHandler:1050-1064` **KHÔNG filter logic** — returns ALL entities. FE query component unknown (fe-user source not easily searchable) but **likely filter EntityType == (Supplier|Detail|Quote)** omit Header+Workflow → Bug 1 Budget (Header type) hidden, Bug 2 Return (Workflow type unlogged vậy). Root cause B1: FE filter skip Header updates OR Schema gap (Header.Update collision: budget vs section 2 edit). Root cause B2: Handler **intentionally skip logging** (no companion audit table like PurchaseEvaluationApprovals for return history). Fix path B1: Option A (add Kind enum — 30 LOC schema+handlers) vs B (extend EntityType — 20 LOC) vs C (FE filter conditional show Budget — 10 LOC FE). Fix path B2: Add `db.PurchaseEvaluationChangelogs.Add()` per mode (15-25 LOC 1 file). Cross-ref pattern memory: S23 t3 lookup bug (Level.Order collision per-NV Mig 29) — schema Mig 29 OR-of-N refactor created similar subtype ambiguity. Surprise: `EntityType.Workflow=5` enum value design-only, unused 4+ mig history. Recommendation: B2 fix first (clear win, 1 file BE), then B1 design (schema + cross-module pattern audit Contracts). Token ~28k.
